Magento : Getting Attribute Code

Question

I am trying to figure out how to get an attribute code from a filter list in Magento.

<?php
$_filters = $this->getFilters();
foreach ($_filters as $_filter)
{
    echo $this->__($_filter->getName());
    echo $this->__($_filter->getAttributeCode()); # color_name
}
?>

getAttributeCode() isnt a method. I want to specify a CSS classname for each filter to the *attribute_code* in app/design/frontend/default/default/template/catalog/layer/view.phtml

Answer 1

The following will work:

foreach($filters as $_filter)
{
    $attributeModel = $_filter->getAttributeModel();
    if($attributeModel) {
        echo $attributeModel->getAttributeCode();
    }
}

The key here is to check that the filter is actually an attribute as some aren't (most commonly categories) and these types of filters obviously won't have an attribute code.
